Skeptical Science New Research for Week #45, 2019

Posted on 12 November 2019 by doug_bostrom

A telegenic thumb on the scales of perception

Kristin Timm reports on presentation habits of television weather forecasters,  in AMS journal Weather, Climate and Society. "Conformal comportment" might be the label on the bucket of behaviors described in Timm's paper, but styles change with time— hopefully. Abstract:

The journalistic norm of balance bas been described as the practice of giving equal weight to different sides of a story; false balance is balanced reporting when the weight of evidence strongly favors one side over others—for example, the reality of human-caused climate change. False balance is problematic because it skews public perception of expert agreement. Through formative interviews and a survey of American weathercasters about climate change reporting, we found that objectivity and balance—topics that have frequently been studied with environmental journalists—are also relevant to understanding climate change reporting among weathercasters. Questions about the practice of and reasons for presenting an opposing viewpoint when reporting on climate change were included in a 2017 census survey of weathercasters working in the United States (N=480; response rate=22%). When reporting on climate change, 35% of weathercasters present an opposing viewpoint ‘always’ or ‘most of the time.’ Their rationale for reporting opposing viewpoints included the journalistic norms of objectivity and balanced reporting (53%), their perceived uncertainty of climate science (21%), to acknowledge differences of opinion (17%), to maintain credibility (14%), and to strengthen the story (7%). These findings show that climate change reporting from weathercasters sometimes includes opposing viewpoints, and possibly a false balance, but further research is necessary. Moreover, prior research has shown that the climate reporting practices among weathercasters are evolving rapidly and so the problem of false balance reporting may already be self-correcting.

Results may vary

With last week's news that the US is withdrawing from The Paris Agreement, the article by Jenouvrier et al The Paris Agreement objectives will likely halt future declines of emperor penguins is as poignant as it is unfortunate in its publication timing. The removal of the largest economy in the world from the input assumptions of the work will surely upend the results. Given that the US has replaced defined objectives with vague assertions of unquantified ambition to be better, we can translate the US decision as a tacit retreat in the direction of "business as usual."  Th situation described in the abstract as it stood prior to the USA's breaking of faith naturally leads to implications:

Here we project the dynamics of all known emperor penguin (Aptenodytes forsteri) colonies under new climate change scenarios meeting the Paris Agreement objectives using a climate‐dependent‐metapopulation model. Our model includes various dispersal behaviors so that penguins could modulate climate effects through movement and habitat selection. Under business‐as‐usual greenhouse gas emissions, we show that 80% of the colonies are projected to be quasiextinct by 2100, thus the total abundance of emperor penguins is projected to decline by at least 81% relative to its initial size, regardless of dispersal abilities. In contrast, if the Paris Agreement objectives are met, viable emperor penguin refuges will exist in Antarctica, and only 19% and 31% colonies are projected to be quasiextinct by 2100 under the Paris 1.5 and 2 climate scenarios respectively. 

Were it not for the successful results of decades of deceit the article's conclusions might not have been superseded so swiftly and sadly. A better-informed US population might not have tolerated such an abdication of pride by "leadership."

  1. Hi, I was looking at asking some climate change questions on the web and thought it would be nice if the Skeptical Science website had a section where we could ask questions. Let me know what you think. 

     

    That's an interesting idea, and timely as we're (slowly) getting underway with an overhaul of the site.  In the meantime, we do closely monitor input from our contact page and highly encourage directing questions there. Questions are a useful type of feedback— we appreciate all  of them and will always try to answer as best we may. .

  2. Actually as a regular reader of this website, thats quite a good idea. I doubt the website people would have time to answer many but other readers may. It could be a weekly thing.
